I resently put on the spoon's N1-muffler
but the engine check light is on
so I ask the spoon's infor
they say the engine check light suppose not to show
if the muffler is set up correctly(which I think I do)
then they say there are two O2 detector in the muffler
the light is on is because the circuit of detector is damaged

I didn't tell them that my S2000 is a USA one(in this way they will answer sooner)
So I am also thinking that because of the setting of computer in USA it may be different from a japanese one
here is the original massage from spoon (if anyone can understand..)

it says:

"engine check lamp (light) coming on is unusual for swapping mufflers. there are 2 O2 sensors on the muffler, the wiring is not defective? We suggest that you go to (in polite form) the store where you bought it from and have them perform a check (on the sensors)."

That's what it said.
